THC is the psychoactive compound found in cannabis and it can be mixed with vape liquids to be taken in a vaporizer. However, the vape pods which led to the problems are thought to have contained another additive called Vitamin E acetate. It’s unclear why this substance, which is clearly not safe for vaping, was put into the vape liquid, although some have suggested that it’s to do with consistency. We’re taking a closer look at the primary ingredients in vape liquids; namely PG, VG, and MCT.
What is VG?
VG stands for Vegetable Glycerin and is a natural chemical extracted from vegetable oils as the name suggests. VG is used in vape liquids to produce dense clouds of vapor and has a sweet taste. VG is also much thicker than PG, making the vape liquid appear more appealing. The other difference between PG and VG is that VG is smoother on the throat and some vapers even vape 100% VG-based liquids. PG and VG are usually mixed in a 1:1 ratio to make vape juice, and then the nicotine, THC, CBD, or flavorings are added into the mix.
Vaping products exist on the market that contains MCT, also known as coconut oil. MCT is rare to find in vaping products but it is available and some people consider it to be safer than PG or VG.
